Seem to work well. Manufactured in 2011 -- cannot find expiration date anywhere so how long can I expect these to last

If you mean Shelf life. A Long time at least 5 yrs possibly 10 but in use It all depends on the load of device they are used in Mine was in the remote for our Lexus and it lasted little over 2-1/2 years so if it has been in use in a device you might want to get a spare ! Keep new batteries in refer. Until needed they last longer when kept cold . And the 2011 is the copyright date not the manufacture date you are right no use by date !

We bought these batteries for the car remotes of a 2009 model we bought summer 2013. Don't now if they were replaced before that. So could last about 4 years depending how much driving you do.

Energizer claims this battery holds its power 8 years if unused (see www.energizer.com/batteries/Specialty/watch-electronic/Pages/coin-lithium-1632bp.aspx). Because 8 years is promised, my guess as an Electronics Engineer is that the maximum useable shelf life may be closer to 9 or even 10 years.

I think you're better off asking the manufacturer. Everyone uses these for various devices and frankly, they would know better.

Sorry I can't help. I have used two and the rest are waiting in case I need them.

I believe they don't have an expiration on them. They seem to last forever.

I bought mine a couple of months ago and they expire on 8/15. I have used expired ones in the past that have worked perfectly.

The ones I just received (March 2014) were dated with EXP DATE 06/2016. Just like the last set I ordered, they have at least two years on them, which is pretty good for Silver Oxide batteries (2-3 year shelf-life)

I also did not see any expiration date on the package. But the 3 I have tried have all worked.

There is no mfg date or expiry date on these batteries. However they worked fine. At couple of dollars and free shipping I am not complaining.

It depends on where you get them. I have gotten mine from Amazon and they have a shelf life of more than a year. Expiration date is printed on the bottom of the container.

I don't remember the expiration date on the package I received, but they were not expired or near expiration. They were effective and worked as advertised. I was satisfied with the results.

The expiration date is August 30, 2014. I did not save any money by buying them on line I just can't find them in the store where I live. They are strange but they do the trick when I am on the move.

I keep them in the refrigerator and could not find an expiration date on the plastic container the solution come in. If they come in a outer box that may have had a date on but did not check before throwing away.

I've been purchasing these for a long time from Amazon, and they are always well within their expiration date. The ones I have now expire late in 2015, but these might have an even better expiration date. I guess to get the exact answer to your question, you could call Amazon.

I don't know if there is an expiration date. I didn't look for one. They were in HP packaging? I hope this helps you. I would order them again.

I have some leftover from a purchase from 2007. They are working fine! Keep them sealed and don't store them in a place that gets hot.

I'm Finished with mine so I can't confirm the brand. Also, each batch would have to have a different expiration date, mine was November 2014, so it would have to be later. I believe I bought mine about a year ago. They do work.

I have purchased these for the past 2 years and each time the expirations have been at least 1 year out. You can buy them, see the dates and then send them back if you need to! I have never had an issue with this.

My printer reads them as expired, but they are still usable. I am still using them.

For some reason, all the sellers want to avoid making promises about expiration dates, ... but the "200" pack that I bought, had over a year left on them.And frankly, ... I've used some that were 2 or 3 years "out of date", ... that still worked just fine, ... so I don't worry too much about dates, anymore.
